[IDEA] Multi-room co-existance

[efung]

I've looked at SnapCast in the past and it did not seem reliable especially since it relies on getting audio data from a FIFO pipe. The fact is that MPD itself doesn't not include multi-room sync audio capability like iTunes, LMS, Roon, etc. Maybe someday a developer will volunteer to write an MPD plugin that does this.

1) would probably turn into a support nightmare for our project.
2) its not possible to have both the on-board audio device and an I2S device active at the same time.

I am not sure what #2 exactly means. But, I have both snapcast server (allows 3 input sources) and client (I2S device) running in the same Raspberry Pi 3B reliably. The second snapclient can play the same music without audible delay. I can "snapcast" the bit streams coming from UPnP client (Qobuz). I also installed BubbleUPnP server to the Raspberry Pi.  I attach the screen captures of my modded GUI.

One of the attached pictures shows moOde Player is playing Halie Loren's songs from Qobuz.

Please post a link to your modified moOde sources, per the GPL.

Will do it after I create a github account for public access.
